Current monostatic radar systems suffer fine tracking and discrimination performance degradation when encountering mainlobe jammers deployed within a reentry complex. As a result our forces may be vulnerable to attack. During Phase I, we have developed di

This proposal will address the development of a digital receiver and exciter (DREX) technology for next-generation scalable missile-defense radar. A DREX is currently being specified at the sub-array level to feed an analog tile or panel subarray. This al

This proposal will address the development of a wideband digital receiver and exciter (DREX) technology for next-generation scalable missile-defense radar. A DREX is currently being specified at the sub-array level to feed an analog tile or panel subarray in order to generate flexible waveforms and beams with improved performance. The technical challenge is to meet the required receiver sensitivit ...

The design and development of scalable panel-based phased-array radars requires the high density integration of solid-state components and adequate thermal mitigation within the array lattice constraints. The current integration technologies such as system-on-a-chip (SOC), multi-chip-module-deposition (MCM-D), and system-on-package (SOP), will help miniaturizing sub-modules for various functional ...

Missile threats faced by our country are constantly increasing in lethality. The weapon used to counter such missiles is the kinetic interceptor. To work effectively, the reentry vehicle (RV) location must be precisely known. Confusing objects within the reentry complex make the key discrimination process very difficult. Coherent distributed aperture (CDA) radar represents an important advance in ...

The objective of this project is to develop a novel expander that can increase the efficiency of cryocoolers for IR sensors at very low temperatures and in remote cooling and across gimbal applications. Miniature Thermoacoustic Expanders (MTAE) that employ high energy acoustic waves generated with no moving parts at the cold expander to produce efficient cooling over a wide range of temperatures a ...

The mitigation of mainlobe jamming is essential to missile defense radar performance. Applied Radar is currently investigating distributed aperture and adaptive processing architectures that promise a new generation of advanced radar performance. Our proposed program will research the application of these distributed aperture radar techniques to determine the mainlobe jammer suppression possible w ...

The design and development of phased-array radars requires the integration of solid-state components and adequate thermal mitigation within the array lattice constraints. The current trend is towards increasingly planar designs and a reduction in the array depth. The MDA SPEAR program is one example in which a planar T/R “tile” architecture is utilized. System-on-a-chip technologies such as Si ...

Positioning and navigation have become a mainstay of everyday life in the U.S.; applications of interest include navigation of vehicles of all kinds, infrastructure mapping, and safety of life systems. Many of these recent applications have become possible through the GPS. With the recognized vulnerabilities of GPS, it is evident that equivalent backup systems must be developed. One possible so ...

MAJOR AIDS TO NAVIGATION (ATON) ARE ESSENTIAL SIGNPOSTS FOR SAFE PASSAGE ALONG COASTAL AND OFFSHORE SEAWAYS. PRESENTLY, THEIR SIGNALS ARE POWERED BY ON-SITE ENGINE GENERATORS REQUIRING CONSIDERABLE AND COSTLY MAINTENANCE. ATON AUTONOMY WILL BE GREATLY INCREASED WITH DEEP DISCHARGE BATTERY TECHNOLOGY PROVIDING THAT ON-SITE CHARGING SOURCES ARE USED. AMONG NATURALLY AVAILABLE SOURCES, THE UNCEASING ...
